List of Intel Pentium III processors

The Pentium III from Intel is a sixth-generation CPU targeted at the consumer market.

Desktop processors

"Katmai"">Katmai (microprocessor)">"Katmai" (250 nm)

9.5 million transistors
All models support: MMX, SSE
The 'B' suffix denotes a 133 MHz FSB
The '80525PYxxx512' number denotes an OEM CPU while the 'BX80525xxxx512' or 'BX80525xxxx512E' number denotes a boxed CPU
The L2 cache is off-die and runs at 50% CPU speed.
"Coppermine"">Coppermine (microprocessor)">"Coppermine" (180 nm)
28 million transistors
All models support: MMX, SSE
The 'B' suffix denotes a 133 MHz FSB when the same speed was also available with a 100 MHz FSB.
The 'E' suffix denotes a processor with support for Intel's Advanced Transfer Cache in Intel documentation; in reality it indicates a Coppermine core when the same speed was available as either Katmai or Coppermine. The 'E' suffix was not used on speeds faster than Katmai was available on, unless the 'B' suffix was also present; but all Coppermine CPUs have the Advanced Transfer Cache.
The L2 cache runs at 100% CPU speed
